L. CARZDELL, E PEARL RIVER; NEW Yeas, AssI NoR o sam FOLDER To all whom it may concern:

Be it known that 1, CHARLES O. L. Can- DELL, a citizen of the United'States, and a resident of Pearl River, Rocklandcounty, State of New York, have invented certain new and useful Improvements in'Sheet- Registering Mechanism for Folding-Ma- ;chines', of which the following is a specification.

The present invention relates to an imjproved construction of sheet reglsterlngmechanlsm for paper-folding machines by' which the-sheets f ed to the'folding machine are simultaneously registered longitudinally and laterally, to insure the proper position of the sheet above the folding rollers, not

- only with regard to the line of first fold, but also with regard to the line of the next succ'eeding transverse fold. In accomplishing this object, Iprovide an end gage which is movable toward and away from the folding rollers and side gages which are movable inwardly and outwardly transverselyof the folding -mac'hine, and means for simultaneously imparting registering motions to the end gage and side registering gages. I pretering gages upon said end gage by means of brackets and transversely reciprocating 'rods and arrange operating mechanism therefor 111 the form of rock shafts geared tothe' operating shaft of the end gage and having rock arms which engage the recipro- 'cating'supporting rods of the side gages to impart the lateral registering motion --to them. The operating shaft is actuate'dby a I suitable cam mechanism to cause t to intermittently rock in its hearings to simultaneously impart the to and fro motions to the end gage and side gages.

In order that my invention may be fully llntlljStOOClfI will first describe the same SHEET-REGISTERING MECHANISM roRrgnnrxqqg vracn' nfis.

Fig; is a side-e1evati0n=of the same. Fig.8-is an inside end 'elevatio'n of the sameyand-Fig. 4 is a detail vertical sectional view taken on the lineelr 'of Fig. 1.

In the drawings 1 have represented-only sufficient parts of a paper folding machine to indicate the 1 operation of, my. improved sheet registering mechanism. 1 represents the frame of the folding machine, 2 and 3 the first-fold rollers-geared together as indicated atr la The foldingknife is: indicated It is well understoodfiin thisv-arti that sheets to be folded are passed into the machine by suitable conveyer tapes to carrythe sheets 'into position'above the folding rollers, the sheet being commonly arrested by a suitablefront gage prioroto itsuregistration for the folding operation. :"llie1sheet is sometimes registered Jeotlr"longitudinally and laterally before it is acted upon-by the first fold rollers and knife andin the present invention provision is made for simultaneously imparting this double registering motion to the sheet. wit-a- 10 represents the end gage which arrests the longitudinal motion of the sheetinto the folding machine and registers i-it lo'ngitw dinally' with relation to the foldingrollers.

'This end gage 10 is preferably-in] the form of-a. heavy plate or bar-;cxtendmg.ftransversely of the machine parallel ivit-l-n;the

as to move longitudinally with the sleeves and at the same time be free to rotate in the sleeves, Any suitable means may be. provided for accomplishing this result, such. for

instance, as the set screws 11 threaded in the sleeves 13 and engaging the annular grooves 15 in the rods 12.

Mounted upon the rear end of each gage supporting rod 12 is a worm gear 16 having a key screw 17 threaded through its hub and engaging the longitudinal spline groove 18 of the rod 12. This arrangement permits the worm gear 16 to rotate rod 12: and at the same time allows rod'12 to move longitudinally through the gear 16, for the purposes.

hereinafter made clear.

An adjusting shaft 20 extends tran's versely of the machine and is journaled in the forked brackets 21 adjacent to its ends. This shaft20 carries between the journals of said brackets 21 the worm gears 22 which constantly mesh with. the worm gear 16 above referred to. One end of shaft 20 carries a hand crank 24. By rotating the shaft 20 the rods 12 may be simultaneously rotated to adjust the end gage 10 toward and away from the folding rollers 2 and 3. Each of the sleeves 13 above referred to is freely mounted in a bracket bearing 25 secured to the frame of the folding machine, and the upper face of each sleeve 13 has formed in it rack teeth 26 which mesh with a gear Wheel 27 keyed to a transverse shaft 28 j ournaled in suitable bracket bearings 29 project ing up from the bearings 25. The shaft 28 has secured to one end a rock arm 30 connected by a link 31 with a lever 32 j ournaled at 33 'upon the machine frame andv having its lower short arm 34 provided with an antifriction roller 35 operating in engagement with a face cam 36 secured to a shaft 37 journaled insuita'ble brackets mounted upon the machine frame and driven in any suitable manner (not shown). A red 38 is pivoted at 39 to the arm 3 1 and extends there-. from through a guide bracket 40 upon the machine frame.

41 is an expansion spring confined upon the rod 38 between the guide 40 and a collar 42 adjustably secured to the rod. This spring actuated rod 38 holds the rock arm. 32-34 in operative engagement with the cam 36.

The end gage member 10 carries a number of forwardly projecting bracket arms in the forward ends of which are freely j ournaled the reciprocating rods 51, extending parallel with the gage 10, and separating in the central longitudinal plane of the folding machine. Adjacent to the outer end of each of the rods 51 is adjustably mounted a side registering gage plate which is presented at right angles to the end gage 10 above referred to. Each of these side gages 55 is loosely mounted at 56 upon one of the rods 51, and is adjustably secured in the desired of the drawings.

position by means of an arm 57 secured to rod 51 by set screw 58 and a threaded rod 59 secured to the rear face of gage plate 55 projecting through the arm 57 and engaged upon opposite sides of the arm by adjusting nuts 60 and 61. In this description it will be observed that each side gage 55 can be adjusted laterally of the folding machine first by reason of the adjustable connection of arm 57 with rod 51, obtaining the general position of the gage, and second, by adjust ing the screw nuts 60 and 61 upon the threaded rod 59. The construction and arrangement of both side gages 55 are the same.

65 and 66 are auxiliary shafts extending at right angles to the operating shaft 28 and jourhaled in bracket bearings 67 and 68. The bracket bearings 67 are supported from the shaft 28 as shown particularly in Fig. 1 Miter gears 70 keyed to the shaft 28, mesh with similar gears 71 keyed to the rear ends of auxiliary shafts 65 and 66 for causing said auxiliary shafts to rock to and fro simultaneously with the operating shaft 28. The forward portions of auxiliary shafts 65 and 66 are longitudi- 68 as indicated at 86, is formed with a downwardly presented bifurcated flange 87 which straddles the shaft 65 or 66 and engages the hub of rock arm 80 for causing the rock arm to move longitudinally of its shaft 65 01'66 when the en g 10 is adjusted 10ngitudinally of the machine.

Each rock arm 80 is formed with a bifurcated lower end as shown at 80 which engages a pin 90 projecting laterally from the block 91 adjustably secured to one of the rods 51. By this means it will be observed that the rocking of shafts 65 and 66 through the mechanism described will cause arms 80 to reciprocate rods 51 in their bearings and move the side gages inwardly and outwardly transversely of the machine.

The operation of my improved registering mechanism will be clear from the following explanation: The registering position of end gage 1O longitudinally of the folder is determined by the hand adjustment of shaft 20 which rotates rods 12 intheir supporting sleeves to move the end gage 10 toward or away from the folding rollers. Since the side registering gages are supported by the end gage 10, it will beclear that they will moye longitudinally of the machine, with said; end gage so that their position adjacent tothe endsof the gage willalways re- 1 time. 7,

been adjusted to the desired positions, the

main the same. To regulate the vgaging position of the side gages 55, said gage plates,

areJa djusted laterally of the machine by their adjustable supporting devices, Either one of the side gages may be used alone by moving the other out of active position, or both side gages may be used at the same lVhen the end and side gages have machine is started with the result that each sheet passing into the machine will be arrested by the end gage 10 and immediately after the arrest of the sheet, said gage 10 will move toward the folding rollers and simultaneously with this movement, one or both of the side gages willbe moved inwardly, for imparting a double registering movement to .the sheet. Immediately after the registry of the sheet, the gages move away from the sheet and the folding action takes place. In the movement of the end gage toward and away from the folding rollers, it will be understood that the cam mechanism rocks the operating shaft 28 which through gears 27, racks 26 and sleeves 13, causes the supporting rods 12 and gage 10 to move longitudinally of the machine. The movement of the side gages is accomplished by rocking of shafts 65 and 66 and their. geek arms 80 acting upon rods 51 upon which gages 55 are mounted.
